kukeltje, thanks for your response it clarified a lot for me. May be you could also comment on persistence a bit: The Alpha version of PVM (http://jboss.org/jbossjbpm/pvm_downloads/) contained some persistence facilities allowing to save process definitions into database tables. In the JBPM 4.0 such facility was removed since process definition is stored as JPDL resource or BLOB now. In our application we still would like to have process structure available through database tables like it was (JBPM_NODE, JBPM_PROCESS, JBPM_TRANSITION etc). What would you recommended to do in such situation? Are there any plans to support database-based process definition persistence in JBPM/PVM?
